Abstract

In this study, MLA-assisted PTT with power modulation was evaluated to compare treatment efficiency with Flat. Human prostate cancer cell was used for in vivo tests into three groups : control, MLA and Flat. 1064nm laser was irradiated 3 W/ cm2 to 1.5 W/cm2 for 60 s. Histological analysis was used to compare the treatment efficiency of application for MLA and Flat, which showed that the MLA group could covered the entire cancer area compared to Flat. In these results, the proposed MLA-assisted PTT can enhance treatment efficiency with a uniform beam distribution for prostate cancer.
